At some point, after being estranged from his daughter, he kidnapped a local girl named Brittany to assume her role, but she tried to escape which resulted in Howard killing her.

Events of the Movie

They spent the following days living in the bunker, until Michelle and Emmett discovered Howard's secret and tried to escape, which resulted with Howard killing Emmett and him dying after the bunker explodes, with only Michelle surviving.

However the explosion attracts the attention of an alien spaceship. Michelle is attacked by both the craft and a creature deployed by it. The craft releases toxic gas, forcing her to take shelter in Howard's truck, which is then picked up by the craft as it attempts to consume her. However, Michelle realized that the gas is flammable and assembles a Molotov cocktail and throws it into the craft, destroying it. After the encounter Michelle leaves the farm in a car.
